摘要： A computer system having a shared disk file system running on on multiple computers each having their own instance of an operating system and being coupled for parallel data sharing access to files residing on network attached shared disks. Methods are provided for use as a parallel file system in a shared disk environment by use of a scalable directory service for the system with a stable cursor, a segmented allocation map. Dynamic prefetch and cached balance pools for multiple accesses improve the system. Extended file attributes are used for implementation of Access Control Lists in a parallel file system. Improvements to caching and cache performance developments balance pools for multiple accesses. A metadata node manages file metadata for parallel read and write actions. For our system, tokens are used for metadata node selection and identification, and we have enhanced token modes for controlling file size, as well as smart caching of byte range tokens using file access patterns and a byte range lock algorithm using a byte range token interface. Locking techniques reduce the overhead of a token manager which is also used in the file system recovery if a computer participating in the management of shared disks becomes unavailable or failed.

摘要： A computer system having a shared disk file system running on multiple computers each having their own instance of an operating system and being coupled for parallel data sharing access to files residing on network attached shared disks. Access to a file by a processor node is controlled by tokens transferred to the node from a token manager. To prevent another processor node from removing a token after the token has been received, but before it performs the operation on the file, each process can lock the token after it has been received. A node with a token can lock a byte range of a file, which byte range may include all or only some of byte range cornered by the token.

摘要： A method and system for allocating blocks of disk in persistent storage to requesting threads. A primary data structure is provided for organizing and categorizing blocks of disk space. In addition, a secondary data structure is provided for maintaining a list of all active file system processes and blocks of disk space used by those processes. Blocks of disk space are assigned to pages. At such time as a thread may request allocation of disk space, both data structures are reviewed to determine if the requested disk space is available and to limit access of available disk space to a single page of memory to a single thread at any one time.

摘要： A system provides referencing from one file system server to another through the use of a file system location database improving movement and replication of file systems. When a file system is moved from a first file system server a data object that references the file system remains in the first server and contains information used to find the current location of the file system. The actual location of the file system is stored in the separate file system location database which contains the locations of file systems on a number of file system servers. This allows the data in a file system to be replicated or moved without requiring updates to the data in any redirecting or referencing servers.
摘要翻译：系统通过使用文件系统位置数据库提高文件系统服务器的引用，从而改善文件系统的移动和复制。当从第一文件系统服务器移动文件系统时，引用该文件系统的数据对象保留在第一服务器中并且包含用于查找文件系统的当前位置的信息。文件系统的实际位置存储在单独的文件系统位置数据库中，其中包含多个文件系统服务器上的文件系统的位置。这允许复制或移动文件系统中的数据，而无需更新任何重定向或引用服务器中的数据。

摘要： A technique for asynchronous computer disk cache management reduces the burstiness of disk I/O. It provides a periodic sync process to flush modified buffers, wherein only buffers exceeding a threshold age are selected to be flushed. In one variant the sync process only executes when the number of modified buffers in the cache exceeds a threshold, which can be dynamically adapted to changing patterns of cache usage. The age of the dirty buffers is measured by sync periods to minimize time computation. In some embodiments an additional cleaning process flushes old buffers between sync invocations.
摘要翻译：用于异步计算机磁盘缓存管理的技术可以减少磁盘I / O的突发性。它提供周期性同步过程以刷新修改的缓冲器，其中仅选择超过阈值年龄的缓冲区以进行刷新。在一个变型中，只有当缓存中的修改的缓冲器的数量超过阈值时，才能执行同步过程，这可以动态地适应于改变高速缓存使用的模式。脏缓冲区的年龄由同步周期测量，以最小化时间计算。在一些实施例中，附加清洁处理在同步调用之间刷新旧缓冲器。
